spiralloop v1.0.2
SpiralLoop
Ever wanted to do a for loop starting from the center instead of a corner? Now you can!
Install
npm install spiralloop
Usage
spiral(Lengths, Center, Function)
Lengths
An array of the lengths of your loop, such as 4, 4 or 5, 3, 7. Handles array lengths as long as you'd like.
Center (Optional)
The default center is in the middle (1.5, 1.5 of a 3x3) but feel free to change this up.
Function
A function that will give paramaters of the current value. For example:
function(x, y, z) { }
If you return true in this function, it will act as a "break".
Example
var spiral = require('spiralloop');
spiral([3, 3], function(x, y) {
console.log(x + ', ' + y);
});
